TOOL FOR REPAIRING TIRES.

To all whom it may concern Be it known that 1, PETER E. ERICKSON, a citizenof the United States, and a resldent of Port Chester, in the county of VVestohester and State of New York, have invented a new and Improved Tool for Hepairing Tires, of which the following is a full, clear, and exact description.

This invention relates to tools or appliances for repairing pneumatic tires and has particular reference to such tools having the capability of ease and reliable manipulation for insertion and for insuring their being held securely in proper position during the treatment of the tires.

Among the special objects, therefore, of this invention is to provide a tool of the character set forth of a neat, light open or skeleton form which maybe easily inserted into the wound of the tire and which will present the least obstruction during the op eration of healing the wound.

The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which- Figure l is a plan view of the device with the jaws in normal closed position; Fig. 2 is a similar view with the jaws spread and locked apart; Fig. 3 is a partial side elevation looking toward the left in Fig. 2; Fig. 4c is a front elevation corresponding to Fig. 2; and Fig. 5 is an elevation of the lever detached.

The several parts of this device may be made of any suitable materials and the relative sizes and proportions thereof may be varied to a certain extent without departing from the spirit of the invention hereinafter specifically claimed.

Referring particularly to the drawings it will be noted that the main portion of the device consists of a frame 10 comprising a pair of jaws 11 and a handle 12. The handle includes a loop 13 having sufficient elasticity to maintain the two jaws in normal contact with each other as shown in Fig. 1. Each of the jaws has a prong 14 extending outwardly substantially at a right angle from the end thereof and terminated in a barb 15. One of the jaws also includes a substantially straight shank 16, and the Specification of Letters Patent.

other jaw a corresponding shank 17 parallel to the first shank and having on 1ts 1nner face a series of pro ections 18 arranged preferably in a straight line.

The prongs 14- and ends of the jaws are adapted to cooperate in close relation to each other and with the points of the barbs 15 terminating in substantially the same point, whereby, when the frame or handle 12 is grasped by the hand 'of the operator, he may readily force the prongs through the wound or slit in the tire, causing the barbs 15 to lie within the same. In order to facilitate the introduction of said prongs as just described, I have found it advanta geous to provide means to prevent one of the barbs from being forced longitudinally of the other during such introduction. I, therefore, provide a brace 19 in the nature of a loop rigidly connected to one of the shanks as indicated at 20', and extending around the opposite shank. The brace being of rigid material and rigidly connected to the shank 16, it will substantially snugly embrace the upper and lower faces of the shank 17 and thereby prevent relative sliding movement between the two prongs when the tool is being forced into place preliminary to spreading the tire. The outer end, however, of the loop or brace 19 is sufficiently spaced, as indicated at 19, from the shank 17 to permit the desired lateral movement of said shank and its jaw.

The expression relative sliding movement as used herein will be understood as having its ordinary meaning as distinguished from a bodily movement of the prongs toward and from each other.

Any suitable means may be provided to positively spread the jaws and hold them temporarily in separated position. To this end I employ a lever 20 of the second class having at one end an eye 21 pivoted at 22 to the brace 19 just within and substantially close to the shank 16. The structure of the brace 19 is cut away as indicated at 19*, whereby the lever may be swung on its pivot outwardly into substantial parallelism with the brace. In the other direction the lever is free to be swung through an angle of about 90 degrees substantially parallel to the longitudinal axis of the handle or frame 10. A shoulder 23 is provided in or on the lever at a distance from the axis of the eye 21 substantially equal to the normal distance tue of said projections, also, the lever will be automatically locked at any intermediate position within the range of the possible expansibility of the frame. The prongs and barbs 14 and 15 serve to retain the device in connection with the tire While the operation is being performed, especially since the weight of the device is comparatively little. After the operation is finished on the tire, a simple rearward swing of the lever will cause the jaws to be sprung together again into normal position by reason of the resiliency of the loop 13, allowing the tool to be easily withdrawn from the tire.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a tool for repairing tires, the combination of a main frame terminating in angularly disposed prongs movable bodily toward and from each other, the intermediate portion of the frame constituting an integral spring loop serving to normally hold said prongs against each other, means to positively force the prongs apart, and a brace carried by the frame and serving to prevent sliding movement of one of the prongs with respect to the other prong in a direction perpend icular to the plane of said bodily movement. j

2. In a tool for repairing tires, the combination of a frame including a pair of straight normally parallel shanks, a pair of jaws extending from said shanks to normal engagement with each other, and means nor mally maintaining said parts in the positions indicated, a brace connected to one of said shanks and extending around the opposite shank, said brace serving to prevent one of said aws from sliding with relation to the other, and a lever pivoted to said brace adjacent one of the shanks and having interlocking progressive cooperation with the op posite shank, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
